It runs on my ancient Galaxy Tab although it doesn’t run particularly well. It mostly comes down to what GPU is in it. I don’t think it’s dependent on OS version at all.
The game turns out to run just fine on my old tablet with a single-core 1GHz CPU and Android 4.0.1 (though admittedly 1G of RAM). Dunno what GPU it has. Haven't played enough to estimate battery consumption, but it doesn't give any signs of stressing the hardware. Good work!
